The color on my PCL542R is off...

The blue lens seems weaker then the red and green. When you adjust the blue focus, it has no effect on the picture. You cannot adjust the blue convergence because you cannot see the blue line to align it. Any suggestions?

When i go to the blue color convergence, The blue + will not adjust at all . The red will adjust like it should but my color on the T.V. is very pale and blurish red. Can I use the adjust pots on the bottom of the three big tubes or the three adjustments behind the front cover ?

If you turn all of the color out of the TV, the picture should be black and white. If that picture is not a true black and white picture, the TV will produce a color picture that has that behind it. It takes the proper mixture of red, green and blue light to produce white. This is something that is done inside the glass picture tube.
In your case, one color (blue is stronger) and the others are weaker.
It probably had not been used for a while. SOMETIMES, the weaker colors will get stronger with use. Adjust the brightness and picture controls to get the closest you can to a black and white picture, and then add the amount of color that seems right to you. Use the TV and hope for the best. It will improve, but 2%, 10%, or 50%; I do not know. The proper repair is to replace the glass picture tube, which is not an option at this time. So, turn it on, play games, and HOPE for the best.

TAKE OFF THE FRONT PANEL AND FIND THE FOCAS ELECTRONIC FOCAS CONTROLS. USUALY BETWEEN THE LEFT SPEAKER AND THE FIRST CRT GUN. PAUSE A DVD WHEN THE CREDITS GOING. OR USE A MENU IN YOUR SAT RECEIVER TO LOOK AT. USEING THE GRID IN THE TV SOMTIMES IS NOT ACCURATE. YOU WILL SEE 6 SMALL KNOBS (RED,GREEN,BLUE)FOCUS AND(RED,GREEN,BLUE)SCREEN DRIVE .FOLLOW THESE STEPS
1 TURNDOWN RED AND BLUE SCREENDRIVE
2 FOCUS THE GREEN (YOU SHOULD SEE SCANLINES)
3 TURN DOWN THE GREEN SCREENDRIVE
4 TURN UP THE RED SD UNTILL YOU SEE RETRACE LINES THEN BACK IT OFF TILL THEY ARE GONE.
5 FOCUS RED (UNTILL YOU SEE SCANLINES)
6 TURN RED DOWN AND TURN UP BLUE
7 FOCUS BLUE (BLUE WILL NOT BE AS GOOD AS RED+GREEN
NOW YOU ARE IN FOCUS, NOW YOU NEED TO GET SCREENDRIVE BACK
THE BEST WAY IS TO, PAUSE A DVD ON A BLACK SCREEN
SELECT PLAY MOVIE AND HIT PAUSE RIGHT AFTER . TURN ALL THE LIGHTS OFF IN THE ROOM AND USE A SMALL FLASHLIGHT TO ADJUST SCREENDRIVE SO YOU DONT MOVE FOCAS BY MISTAKE.
THE TRICK IS TO END UP WITH A VERY FAINT GRAY SCREEN WITH EACH COLOR UP AS FAR AS YOU CAN WITHOUT SEEING ANY COLOR ON THE TV. WHEN YOU GET THIS TRY PLAYING THE MOVIE. MAKE SURE THE BRIGHTNESS AND CONTRAST IN THE TV ARE AT A NORMAL LEVEL BEFORE YOU START . COLOR,BRIGHTNESS,AND FOCUS IS NOW SET TO YOUR DVD PLAYER.DO A FINAL CONVERGANCE AND YOU ARE DONE!
IF YOU CAN'T GET A COLOR TO FOCUS YOU MAY HAVE TO DO THIS MANUALY. SOME TV'S YOU CAN LOOSEN THE NUT ON THE CRT LENS AND MANUALY FOCUS IT. (LIKE AN OLD CAMERA). IF YOU GET THIS FAR YOU MIGHT AS WELL CLEAN THE LENS WITH A VINEGER BASED GLASS CLEANER (SPRAY THE RAG NOT THE TV) TAKE A LOOK AT THE MIROR, CLEAN IF NEEDED. IF THE MIRROR IS REAL DIRTY THEN THE SCREEN MUST BE BAD TOO.TAKE THE SCREEN OFF AND CLEAN THE BACK SIDE IF NEEDED. LOOK INTO THE LENS AT THE PICTURE TUBE YOU SHOULD SEE A NICE BRIGHT CLEAN PICTURE IF IT LOOKS CLOUDY YOU NEED TO CHANGE THE LIQUID IN THE CRT GUNS.I DON,T THINK YOU WAN'T TO TRY THIS YOURSELF.
TIP(I USE A LITTLE ARMOR ALL WHEN I CLEAN LENES, THIS REPELS DUST LIKE IN YOUR CAR) IF YOU CHANGE YOUR FLUID AND WANT TO KNOW WHERE TO GET NEW FLUID I PUT CLEAR ANTIFREEZE IN MY PIONEER TV 3YEARS AGO AND STILL LOOKS GREAT "NOT KIDING"
HOPE ALL THIS YOU. IF YOU ARE NOT COMFORTABLE TO DO IT. HAVE IR SERVICE. REPAIRING THIS WILL BE YOUR BEST OPTION>THANKS

You have a focus/screen control box Find it and adjust the R/G/B screen drives When you first start Go to Menu turn Color off then with a mirror adjust the picture as close as you can to a black and white picture R/G/B screen drives, the little control box you are looking for will have 3 controls on top for focus and 3 controls under them for screen drives to each tube red,green,blue after you have adjusted to a black and white picture then go back and turn color on.

Most of these sets have a SCREEN/FOCUS block---usually all black with 6 controls----you need to look close at it as one row of 3 will be screen controls---don't touch those----the other 3 will be FOCUS- MARKED in little letters will be r,g,b(red,green blue). TWO ways to adjust the focus: 1. carefully locate the blue focus control and adjust to see if blue will improve in focus. 2. each of the 3 large lens where the picture comes out have a wing nut and a slot--you can loosen the nut and turn the lens---usually best focus that way is if the part that turns is in the middle of the available area to move it.

I should point out that all projection sets intentionally de focus the blue--the lines if blue should be clear but never as perfect as green or red--this is normal.

I do this here for free so if this has been helpful give me a vote here.

The tv has 2 focus adjustments for each tube, mechanical and electrical.

1. Mechanical focus is set by looking at screen from back (through inspection plate on back of most samsungs) and rotating the lens assembly on CRT. loosen wing nut and turn lens assembly to go through focus and back to best position.

Put convergence pattern on screen and manually misadjust bottom red and green lines convergence so they can be seen through inspection hole.

With back cover of TV off you can usually reach your hand up beside the lens assembly to loosen the wing nut then rotate to adjust. Green is in the middle. The focus will be obvious when you rotate and look

When you are finished make sure the foam dust protector is not over any of the lens assemblies and the wing nut is tight.

2. Electrical focus - located at front of unit. the front grille/speaker cover is removed and maybe a cover over the front crt inspection hole.

In the inspection hole there is a black plastic "Focus/screen adjust Assembly" with 2 rows of 3 controls.

One row is focus and the other is screen. The middle controls are for green with R/B on either side. Usually the controls are labelled as "focus" and "screen". You want to adjust the focus controls, one for each color. Look for the focus or screen label imprinted in the plastic. Don't play with the screen settings.

With the same misadjusted convergence pattern you can see a red, blue and green line. Adjust green focus and watch green line for best focus. Do same for other 2.

Screen adjustments are very exact and delicate. The easiest way to deal with them is to turn color off in Customer adjust menu. Put any color tone adjustments in the middle (low, med, high, put at med).

You should have a b/w picture if there are no crt or other color related faults. If it is close to B/W leave screens alone.

If the pix is too green, then the green screen setting must be reduced a small amount. Do not play with these adjustments as most TV repairrers have a difficult time adjusting them.

If focus adjustments don't help then focus control or CRT may be defective. Needs expert to determine.

Hi,
I'm not sure about this model but most projection tv's have a focus/screen control block usually located behind the front grille where the speakers are. The grille usually comes off easily. If there are no circuit problems you can adjust the red green and blue picture tubes there. Also the focus. It will be written somewhere screen and focus: Three for screen and three for focus. If you find the screens then adjust them slowly clockwise for increase brightness on the red and blue and you may have to reduce the green. Adjust for best picture. If the picture does not adjust too good then the tubes are weak. Only if there are no circuit problems Hope this helps

Your missing the red drive on the set. Its most likly the picture tube. Its a possibility that the red drive circuit could be not working so the best thing to do is take off the gree picture tube socket and put the green board on the red tube. Of course do all this when the set is unplugged. if you have no tv experience. its not a good idea to be messing around inside of these sets.
